Figure 8: Colorimetric assay of caspase-3 activity of lectin on cancer cell MCF-7. Normal and treated with lectin extract at 0.02 μg/ml (A. flavus) at 37°C for 48 h, DEVD-CHO is a Caspase-7 inhibitor. The results shown are the representatives of three independent experiments. The treated samples showed significantly increased in caspase activity compared to those untreated (control) and caspase inhibitor (P<0.05).
